string val = string.Empty;
if (yourInteger != 0)

I am trying to print to a receipt printer during our payment process.
The printer is not the default printer and I can't change that.
The problem is that from the browser you don't have permission to programatically get
a list of printers and select which one you want. So, currently we pop up the Print dialog
then select the desired printer and then click ok. This is two steps too many.
How can you get around this limitation and automate the printing of the receipt?

No, you cannot. As you said, in javascript, you can kick off the printing process, but you can't interact with it.

So, I guess we could create a client side windows web service which accepts the html and then have the web page post to it and then it could do the printing.

Well, a client side app that calls a web service, yes, that would work. Or an ActiveX control perhaps.

Yes, I didn't what to do an ActiveX control but either way it is a client side solution.
thanks for your input.

Hi all
I am using ASP.NET 3.0 and I have a list box in content page. I am using Master Page architecture. I am binding data from the database into the listbox. but it gives me error of "object reference not set to an instance of an object". This is what I am doing..
((ListBox)(this.FindControl("ctl00_ContentPlaceHolder1_lMondayFD1"))).DataSource = ds.Tables[0].DefaultView;
Please guys any one can help me
|

Are you able to find other controls at the same place ?
OR can you try like below :
Note: Be sure if your Listbox control defined in Content Place holder
ContentPlaceHolder mpContentPlaceHolder;
ListBox lb;
mpContentPlaceHolder = (ContentPlaceHolder)Master.FindControl("ContentPlaceHolder1");
if(mpContentPlaceHolder != null)
{
lb=(ListBox ) mpContentPlaceHolder.FindControl("yourListboxid");
if(lb!= null)
{
lb.DataSource = ds.Tables[0].DefaultView;
}
}
OR In case List box placed on Master page then use try like this:
ListBox lb = (ListBox ) Master.FindControl("yourListboxid");
if(lb!= null)
{
lb.DataSource = ds.Tables[0].DefaultView;
}

Background:
We are using .NET 2.0 with the MS Ajax Extensions and the Ajax Toolkit. I'm using the Ajax ModalPopupExtender extender control to create modal popups on a page. I am using a custom datepicker control that uses javascript to pop up a calendar, and populates the textbox with the date selected.
Problem:
It seems that Javascript gets confused with the z-index of the popup. When used on a non-ajax popup panel, it works flawlessly. But, when it is placed on a modal popup panel, the javascript popup calendar is shown behind the modal form. Since the main form and the panel that is controlled by the modal popup are essentially the same form, the control cannot distinguish that its z-index should be set differently.
Failures:
I've tried moving the panel to the beginning of the page.
I've tried setting the z-index of the page to a high number
I've tried setting the z-index of the panel to 0 and 1
I've rechecked the code to verify it is not setting the z-index internally.
Any help on finding a solution to this problem would be greatly appreciated.

I'm looking for a way to make an applet communicate with the same aspx page it was loaded from and not a new one. Using the http protocol I'm able to connect the applet to the aspx, but it is a different one and I need to be the same since every aspx contains diferent information (data members).

If you are using a trusted connected then you have to remember that your ASP.NET application runs as a different user to you. So, when you connect using the wizard in Visual Studio you are using your credentials. When your applications runs then it is using the credentials of the ASP.NET process (normally NT AUTHORITY/NETWORK SERVICE). You have to give permission to that account in your SQL Server.

Hi!
I'm newbie in ASP.NET world, but I read a good book about it.
My question is:

I'd like when an user change any data in any control, and then he/she try to close the browswer or try to leave the web page without save the data, it appear a message box warning that he/she will lose the changes.
Do you have any idea?
Thank you in advance.

I believe these options are configurable whilst writing a PDF file but I don't think Office documents give those flexibilities/facilities.

I have a single webserver using win 2k8 and IIS 7 that is not on a web farm. For one particular page I keep getting one of these 2 errors when any event is executed on the page
Most of the time it is the viewstate error.
This error only happens in Internet Explorer 6 and 7.
I have used firefox and safari and everything works just fine it only happens in IE.
I have a chack box list and a couple of drop down lists on my page as well as a gridview etc.
I tried changing the machine key to no avail so i changed ot back to auto generate
I had read an article where you coudl store viewstate as a session but was not sure how to do that in VB.net
Any ideas how I can correct this?
Thanks
Here are the errors
Viewstate verification failed. Reason: The viewstate supplied failed integrity check.
Forms authentication failed for the request. Reason: The ticket supplied has expired.

One possible cause is that your asp.net pages are not inheriting from System.Web.UI.Page, i had that problem when i converted to .net 3.5, but i've never used IIS7 or win 2k8, so i'm afraid i cant be more help.
Alcohol the cause of and solution to all of life's problems.
